What is the reason why an electric bike can t outrun a motorcycle?

This big sister! Let's analyze the reasons for you from the following points:

1.The battery car does not need to drive the license and does not need to go through the driving school to learn, so when dealing with emergency situations, it is often impossible to choose the correct operation! It turns out that the battery car is reversed, and there are more people who run red lights than motorcycles!!

2.The cost of the battery car is low, the car itself is light, and the materials used in each component are not very strong! Imagine, for the sake of driving safety, stability, and the weight of the battery car increased to more than 300 pounds, how much power of the motor is needed? Will the female compatriots still choose???

3.That is, the reason for the popularity of battery cars is that they are lightweight and cheap, and battery cars are designed to be like motorcycles, so how much power does it cost? I guess this money can play a QQ car!

A few points upstairs make a lot of sense!

In addition, there is an important reason for the different power sources, the motorcycle uses a gasoline engine, no matter the flat road or slope can run fast, the maximum power is more than ten or even dozens of horsepower, and the energy is stored in the fuel tank; The motor used in electric bicycles, not to mention the volume of the motor with tens of horsepower, the current during high-power operation makes the battery (livestock battery) that stores energy unbearable!

Can I only run 35 miles with a racing-style electric car on the same battery, but the speed is 40 yards! I can run 65 miles on a small electric car, but only 28 yards!

One thing, you're right, can overtake motorcycles! But do you think about it? What a battery is needed for such a fast speed!

The battery should be at least the size of a sofa! Do you put **? If the cost of such a large battery is reduced and replaced with a lithium battery, then his ** is more expensive than a motorcycle!

High-end electric vehicles run a lot faster than motorcycles, but the cost is several times more expensive, mainly the battery, followed by the motor.

A few points upstairs make a lot of sense!

Analysis of the reasons why electric cars can't go far

1. The charger does not match the battery, or there is a quality problem with the charger. There are many families who now have two or even three electric vehicles, and they will choose to share a charger for the convenience of charging.

2. The motor has been demagnetized or aged. If there is water ingress into the electric vehicle motor, then its interior will rust and demagnetize, which will reduce the energy conversion rate and the electric vehicle will not be able to run far. In addition, if the motor itself is a refurbished motor, then it has the problem of aging, and the aging will also reduce the energy conversion rate, and the electric vehicle will not be able to run far.

3. The controller is aging, which shifts the undervoltage value parameter. If there is an aging problem in the EV controller, then the undervoltage value parameter will be offset, resulting in the battery being consumed prematurely and not running far.

Care instructions. 1. The use of electric vehicles should be kept in a fully charged state, which can prolong the battery life. If you encounter snowy road slippery or uphill, headwind, or heavy loads, you should try to use manpower riding to avoid impact damage to the battery.

2. Store the electric vehicle in time, do not let the melted snow water flood the center of the hub and cause unnecessary losses, at the same time, in order to avoid battery leakage caused by frost condensation, the battery temperature should rise to the indoor temperature close to the close and dry before charging.

What is the reason why the electric motorcycle does not run fast Dear, hello, the problem may be one: the battery is insufficient. We often find that when the battery is about to run out, even if the knob is adjusted to the fastest position, the speed cannot go up, and the driving is intermittent.

Because the electric vehicle controller has under-voltage protection, such as the under-voltage point of the 48V battery is 42V, the under-voltage point of the 60V battery is 53V, and so on. When the power is used to the undervoltage point, the speed of the car will slow down, which is a kind of protection for the battery. This problem is not called a problem, as long as it is fully charged, it can be solved.

Problem 2: Speed limiting device. Since the current standard for electric vehicles is the old national standard in 1999, one of the requirements is that the maximum speed is not more than 20 yards, otherwise it is an over-standard car, can not be licensed, once there is a traffic accident manufacturers to be responsible.

Therefore, many manufacturers install a speed limit line when the new car leaves the factory, and as long as the line is cut, the speed can be increased. Problem 3: Motor demagnetization.

Frequent overweight and overload will weaken the magnetism of the motor and demagnetize the magnet; If the motor demagnetization, which also occurs under strong vibrations or excessive temperatures, all demagnetized motors will have a decrease in power and a slower speed. Problem 4: Handle problem.

If the contact resistance of the plug is too large, it will also cause the motor to rotate slowly and drive hard. Detect the voltage of the speed regulating handle speed regulating signal line (green line), and when the handle is at the maximum angle, the voltage at the speed regulating end should be. If it is less than this voltage, it will cause the electrode speed to slow down, and the speed regulating handle should be replaced.

Problem five: Failure of the third gear shift. Many electric vehicles are installed with a three-speed shift device, which can speed up the commutation frequency through the controller to achieve gear shifting, increase the output current, and increase the motor power.

When the shift switch is put in normal gear, it will be significantly slower than overtaking. Problem 6: The controller is malfunctioning.

The speed of the vehicle is determined by the speed of the motor, which in turn depends on the current of the controller. The current distributed by the controller is different, the larger the output current, the faster the speed, and the mismatch between the controller and the motor power will also lead to a slower speed. Question may be seven:

Insufficient tire pressure. Whether there is enough gas in the tires also has a great impact on the riding of electric vehicles. If the tire gas is insufficient, it will increase the resistance of the electric vehicle to move forward, which will not only consume high power, but also affect the speed of the vehicle.

Problem Eight: Brake failure. If the front brake is not used often, the rust causes the brake to collapse, the finch arm is inflexible and difficult to return to position, accompanied by brake resistance, slowing down; If the brake pads on the rear wheels fall off or if a foreign object enters the brakes, it will also affect the slowdown.

Even if the brakes are not bad, sometimes too tight can rub the wheels and reduce the speed of the car. The above eight problems are the main reasons for the slowdown of electric vehicles at present, of course, if faced with objective factors such as headwinds, uphill, and overweight, the speed will also slow down. When the electric car suddenly slows down, you should go to a professional maintenance point for inspection in time.

However, electric vehicle observers remind everyone not to ride too fast and pay attention to obeying traffic rules.

The speed of an electric car depends on the speed of the motor.

The controller only controls the speed of the motor rotation, provides the signals necessary for the motor to rotate, etc. The power and design speed of the motor determine the speed of the electric vehicle. The faster the motor speed, the faster the electric vehicle will be.

The controller only controls the speed of motor rotation, provides the necessary degree signal for motor rotation, etc., although there is overcurrent protection in the controller, but only plays a role when the motor fails, and is only responsible for transmitting the power to the electric qi vertical machine during normal driving, and the power of the motor, the design speed of the land crack determines the speed of the electric vehicle.

1. Work within the allowable power range of the motor, and the speed of walking is only related to the speed transmission ratio, and has nothing to do with the motor;

2. In the case of the state of the motor, the battery voltage, the controller, and the rotating parts of the car are well matched, and the transmission ratio is still marginal, the electric vehicle is still slow, that is, the power of the motor is too small, and the motor power overload will be overloaded and heated.

The electric car is not fast when it leaves the factory? The main thing is the controller, which has something to do with the power of the motor, and if it is the old one that is getting slower and slower, it is the reason why the permanent magnet of the motor is gradually demagnetized.

The first one has to do with the battery, and the other has to do with the motor.

The size of the motor is related.

When new energy electric vehicles first came out, the basic range was in 200-300km, many times do not meet the needs of our travel, as long as the electric car is a little farther away, the electric car may not go, and the use must be frequently charged, the anxiety of short battery life has also been generated, and this has become a major reason to dissuade consumers from choosing new energy electric vehicles, suppressing and limiting the development of electric vehicles. In order to break through this limiting factor, new energy vehicle companies have also made great efforts, through a series of practices such as increasing battery volume, improving battery energy density, reducing energy consumption, and improving kinetic energy, the mileage of today's new energy vehicles continues to break through, and many new products of car companies can reach 600-700km of endurance, and the previous GAC Aion LX PLUS range is more than 1,000 km.

However, everyone found that no, the range of a fuel car is generally more than 500 kilometers, but no one complains that the battery life is not enough, and the range of electric sail cars has not changed the range anxiety of consumers even if it has exceeded that of oil cars, and even reached 1,000 kilometers, so where does the range anxiety of electric vehicles come from? The power of electric vehicles** is the power battery on board, and its anxiety basically comes from this. The first is the lack of the power battery itself, whether it is a lithium iron phosphate battery or a ternary lithium battery, its energy density is capped, before the development of new battery materials, the best way to extend the battery life is to increase the volume of the battery, but if the volume of the battery is too large, it will inevitably compress the space in the car, and the driving experience will not be added, so the volume of the battery needs to be controlled within a reasonable range.

Of course, the energy density of the battery can also be improved by changing the electrode material, for example, the "nickel" element in the ternary lithium battery will affect the energy density of the battery, and a higher energy density can be imagined through his proportion, which is the case with NCM811 batteries, but due to the excessive activity of nickel and poor stability, the safety of the battery will be affected. As consumers pay more attention to the safety of electric vehicles, many car companies have begun to switch to safer lithium iron phosphate batteries. Secondly, the charging of electric vehicles is also a major problem.

The data shows that the number of public charging piles in China has reached 10,000 units, and the overall number of charging piles has reached 10,000 units, but compared with the number of 10 million new energy vehicles in China, it is still insufficient. Of course, the most important thing is that the charging efficiency of electric vehicles is too low, it takes about 10 hours for a car to be fully charged and used for slow charging, and even if it is fast charging, it takes about 40 minutes, especially when traveling on holidays with hail, queuing for charging is the norm.

Causes of self-discharge of the battery. This phenomenon is still very common in real life, for example, many people are used to charging directly after the battery is used up, and after the power is fully charged, it will be placed in the garage for direct use next time, but in fact, it is possible that it will not be used again for a long time, in this case, because the battery of the electric vehicle has the phenomenon of self-discharge, the longer the storage is not used, the greater the power loss, and the faster the battery voltage will drop.

When you ride again after placing it for a long time, it is easy to cause a situation where it is obviously full of electricity, but when you want to accelerate at the beginning of running, you will directly drop two grids of electricity. To avoid this situation, you must often ride an electric car out, and electric vehicles cannot be put on the shelf for a long time. In addition, when installing the battery, be careful to avoid connecting the external metal to the positive and negative electrodes of the battery.

Introduction:

It may be the effect of cadmium-free battery. In the past, there was a heavy metal cadmium in the battery, which has the characteristics of corrosion resistance and long life, and the stability is relatively strong, but because cadmium is a heavy metal, it is extremely harmful to the environment, and the impact on the human body is not to be underestimated.

If the electric car can't run far, in fact, this is mainly because of the problem with your battery, like this case, you can consider replacing a new set of batteries, if your battery is no problem now, just replaced with a new battery, then it is very likely that your motor has a problem, it may be that the motor is now consuming too much power, there may be internal wear, which leads to friction between the stator and the rotor, resulting in a decrease in energy conversion rate, which will also lead to insufficient mileage of your vehicle, So this can be used to test the motor, if the motor is not a problem, then you have to consider replacing a controller, which also has a lot to do with the controller.
